about servicing and parts

Rs.5,00,000 to Rs.6,00,000

Service Charges: 450-550/- (Includes oil change & servicing)
Variation depends on the city.
Parts r not that expensive - mostly the electronic chip controlling the injection systems gets out of syn which would be replaced by the company within the warranty period.
Ownership of Diesel is slightly higher when it comes to replacing parts. But then its totally based on the kind of damage. I'd say ownership of a diesel is about 20% more than petrol in terms of running costs. But then u will save the same on fuel prices & the millage you'd get on diesel.

Servicing:
1st: 1000kms
2nd: 2500-3000kms
3rd: 10000kms
and so on.

Getting the engine oil replaced & carburetor cleaned every 2000kms helps improve the average a lot.
For the extra 70k u spend on a VDi is definitely worth it if u intend to own it for over 5yrs. Petrol prices will soar in times to come but Diesel being an agricultural commodity - remains less prone to erratic hikes as the govt. keeps a control on it.
